With the advent of internet and websites that cater to the aspiring
students' needs, it is not so hard to find past papers of the JEE exam.
There are many websites that provide upto 10 years' old papers for
practice, in the form of questions or even solved ones. It is believed
widely that only studying for the examination syllabus is not sufficient
to ace the exam.

The advantage of keeping old papers and practising from them is
that, most questions on the JEE are of the same nature, only the
application principles differ. The syllabus for the IIT-JEE has remained
the same for the last 15 years or so. The tested concepts are the same
every year. Hence, first the topics need to be crammed up and only
secondly, the practice papers must be used. Using these also give one a
clear idea about what kind of questions appear in the test and what the
standard of the tests will be.

The best way to utilize these is to take tests in a timed
environment with no distractions around. For students to be successful
in the JEE main, they should be both quick and accurate in their skills.
Also in order to maximize your score in JEE you need to be good in all
three subjects i.e. Mathematics, Physics and Chemistry. Most of the
times students give more attention to a particular subject and topic
which is not the way to crack IIT-JEE, to be sure of results give equal
importance to all three subjects, practice more and more questions on
each subject.
